SPECIFICATION forming part Of Letters ZPatent NO. 621,596, dated March21, 1899.

Application filed January 14,1899. Serial No. 702,120. (No model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES A. BEHLEN, residing at Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Thill-Oouplings, of which the following is aspecification.

My invention relates to a thill coupling. The object of my invention isto provide a readily-detachable and antirattlingcoupling. The featuresof my invention will be more fully set forth in the description of theac companying drawings, making a part of this specification, in which-Figure 1 is a central elevation of my im-, provement attached to acarriage in position for use. Fig. 2 is a top plan view thereof.

.Fig. 3 is a detached sectional elevation of the coupling andjournal-bolt. Fig. 4. is a plan View, partly in section, of thejournal-yoke. Fig. 5 is a modification of the method of attaching thecoupling-iron to an ordinary thill.

A represents the axle, and A the clip. It is provided with a bifurcatedcoupling-head, preferably formed integral with the clip-iron. The jawsof the bifurcated arms a are pierced to form a journal for a revolublebolt D. d represents a sleeve incasing said bolt, formed of vulcanizedfiber or other antirattling material.

B represents a coupling-head, slotted so as to hook onto thejournal-bolt D. It is rigidly attached to the thill, as shown in Fig. 1.

It will be observed that when the set-screw is turned out of engagementwith the coupling-head the yoke G will swing freely backward and allowthe thills to be unhooked; but when the yoke 'is brought into rigidengagement with the coupling-head all lost motion is taken up, thecoupling is firmly secured in position, and rattling of the coupling isprevented.

I have shown in Fig. 5 a'modification which allows my improvedcoupling-head to be attached to the ordinary thill outside of theordinary eye-coupling without the necessity of removing the same, sothat the ordinary thill can be readily converted to receivethy-readilydetachable and antirattling coupling.

It will be observed that my thill member is curved upward and that thehook in the end of this upturned thill is open downward, the recess forthe thumb-screw being in the top. This enables the shaft member to becoupled by simply lifting the shaft from the floor high enough to allowthe hook to readily pass over the journal-bolt. The weight of the shaftthus helps to hold the coupling, the yoke is swung forward, and thescrew turned, so that there is little manipulation required either ofthe shaft or looking parts. 4

Having described my invention, what I claim is In athill-coupling thecombination of a couplinghead,aj ournal-bolt secured between thebifurcated arms, a yoke pivoted to said bolt outside of said arms,-athumb-screw tapping through said yoke, an upwardly-curved thill-ironprovided with a hook at its end opening downwardly, and a notch in theupper exterior surface of the hook, adapted to be engaged by the innerend of said thumbscrew, substantially as specified.

In testimony whereof I have hereunto set my hand.
